RAM, or Random Access Memory, is a kind of computer data storage, which allows the information to be read randomly without accessing the preceding bytes before that. That makes the RAM noticeably faster than other sorts of storage devices like DVDs or HDDs where all the info ought to be read in order to access specific data. In case you have a shared hosting account, the total amount of memory that your web apps can use can't be fixed and may regularly depend upon the free memory which is available on the physical server. Using a standalone web server, however, there is always a minimum amount of physical memory that'll be at your disposal at all times and will not be allotted to other customers even when it is not being used. That is valid with our virtual and dedicated servers.
